Problems solved by technology

At present, the anchor bolts are usually pre-embedded directly, and then the steel bars are fixedly connected to the steel bars of the concrete foundation. This connection method is easily disturbed and displaced during concrete pouring, which seriously affects the installation quality of steel pipe piles, especially For the anchor bolts of circular steel pipe piles, a deviation may cause the entire steel pipe pile to be unable to be installed in place

Embodiment

[0037] refer to Figure 1 to Figure 9 , a construction method for locating the anchor bolts of the embedded column foot of a steel pipe pile, which includes the following steps:

[0038] Step 1, specific reference figure 1 , construction foundation pile hole 5, the diameter of foundation pile hole 5 is 3.3 meters, then pours reinforcement cage 51 and pouring concrete for the first time into foundation pile hole 5 successively, the first time concrete is poured to the hole top 4.4 meters away from foundation pile hole 5 m, forming a concrete layer 91;

[0039] Step 2, specific reference figure 2 with image 3 , install the anchor bolt positioner on the foundation pile hole 5;

[0040] The anchor bolt locator includes a locating ring plate 1, a locating column 2 and several sets of bolt connectors;

[0041] The positioning column 2 is a rectangular hollow tubular structure arranged vertically, and an annular positioning frame 21 is coaxially arranged near the middle thereo...

Abstract

The invention provides a steel pipe pile embedded type column foot foundation bolt positioning construction method. The method comprises the following steps that 1, a foundation pile hole is constructed, and concrete is poured to form a primary concrete layer; 2, a foundation bolt positioner is installed, the foundation bolt positioner comprises a positioning ring plate, a positioning column and a plurality of bolt connecting pieces, so that the bottom surfaces of foundation bolts are positioned 0.2-0.5 meter above a primary concrete layer; 3, the foundation bolts are positioned and adjusted, and then the concrete is poured into the foundation pile hole to form a secondary concrete layer; 4, a bearing platform is excavated to form a bearing platform construction position; 5, the steel pipe pile foundation bolt positioner is dismantled, and the foundation bolt is reserved and pre-buried in the secondary concrete layer; 6, a steel pipe column is installed; and 7, the bearing platform is constructed. According to the steel pipe pile embedded type column foot foundation bolt positioning construction method, pre-burying construction of the foundation bolt group on a concrete foundation can be efficiently, integrally and accurately achieved, and rapid, efficient and accurate pre-burying construction of the foundation bolt group in the foundation pile hole can be achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for positioning anchor bolts of embedded column feet of steel pipe piles. Background technique [0002] The pre-embedded construction of steel pipe pile anchor bolts has always been the key to the precise positioning of steel pipe piles. At present, the anchor bolts are usually pre-embedded directly, and then the steel bars are fixedly connected to the steel bars of the concrete foundation. This connection method is easily disturbed and displaced during concrete pouring, which seriously affects the installation quality of steel pipe piles, especially For the anchor bolts of circular steel pipe piles, a deviation may cause the entire steel pipe piles to be unable to be installed in place. Therefore it is necessary to improve. Contents of the invention [0003] The purpose of the present invention is to propose a construction method for posit...
